Specification of Letters Patent. Patented Apr. 1?, 191 Te Application filed April 1, 1916. Serial No. 88,274.

To all whom it may-concern:

Be it known that I, ADoLPH W. LISSAUER, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Nozzle, of which the following is a full, clear, and exact description.

My invention relates to nozzles for generating a spray of liquid in a finely divided state. It constitutes an improvement on the structure disclosed in my pending application filed January 27, 1916, the serial number of which is 74,681. The object of the invention is to provide a simple and inexpensive nozzle Which will otter the least re- 'sistanc t0 flow therethrough, which will not clog, which can be easily cleaned during the operation, and with Which a maximum amount of liquid can be delivered with a minimum of initial pressure.

With the above and other objects in view, the nature of Which will more fully appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts as herein fully described, illustrated and claimed. In the accompanying drawings, forming part of the application, similar characters of reference indicate corresponding parts in all the views.

Figure 1 is an elevation of an embodiment of my invention;

Fig. 2 is a vertical section through the the distributer being housing of the nozzle, shown in elevation;

Fig. 3 is a section of the distributer, the tip being shown in elevation disconnected from the distributor; and

Fig. i is a horizontal section on line 44, Fi 3.

I teferring to the drawings, the housing 6 of the nozzle is formed of a tubular portion 7 having at one end a polygonal base 8 to be engaged by a wrench. The other end of the tubular portion is provided with' a tapering dome 9 terminating in a fla d opening 10. The angle of the flare with the vertical is about The tubular portion at the base has a shoulder 11 against which a threaded base collar 12 of a distributer 13 abut's when the distributer is screwed into the housing.

The base collar 12 of the distributer is surmounted by a cylindrical portion 14 fitting snugly into the tubular portion of the properly spaced are in a plane at right planes being formed on housing. The cylindrical portion 14 is dominated by a reduced cylindrical portion 15 which has a tapering part 16 at the top from the tapering dome 9. The base angle of the tapering-part 16 is greater than the base angle of the tapering dome 9; consequently, the distance between the two tapers decreases as the outlet of the nozzle is approached. v

The tapering part 16 of the distributer has an axially-threaded bore into which the stem 17 of a distributer 18 is screwed through the flared opening 10 of the dome. The deflector has a tapering curved surface 19 facing the flared opening 10. The tapering surface 19 opposite the flared opening is parallel therewith; but at the margin the angularity of the tapering surface 19 increases and is substantially...

The size of the stem between the distrib- 21, which is to supply the liquid to be sprayed. The portion 22 above the end of the pipe 21 has a capacity such that the static pressure of the liquid is kept substantially constant. Two diametrically opposite passages 23 extend from the portion 22 into the annular space formed within the housing 6 of the distributer. These two. passages angles to the axis of the nozzle. I I

Each passage enters the annular space formed by the housing 6 and thecylindrical portion 15 of the distributorv below the .high end of an inclined plane 24,'each of said the cylindrical portion 14 and partly encircling the cylindrical portion 15 and forming an integral part therewith. The inclined planes are made as short as possible to eliminate friction and the tendency of the liquid moving thereupon to clog within the housing. The passages 23 are so formed in the distributor that direct the liquid against the inner surface of the tubular portion 7 at as small an angle as possible, the object being to secure the conversion from static to velocity pressure with the least frictional loss.

1. The herein described nozzle, consisting of a housing having an internally threaded base and a, cylindrical portion shove the hase and terminating in e dorne provi-i cl with a flaring opening e. distributor having an exteriorly threaded hsse and two cylindricel portions of different disrneters, smaller one of which a teperi provided with threaded socket trihetcr having on exterior of lindricel portions ogpositely inclin feces and provided with a bore n rnsters opening at ti l inclined snrr Elector having; a stern. opening of the honsi; o. i} threaded end engo the socket disti'ihuter.

e. "lhe nozzle herein described com; ing: a housing having a dome shaped provided with an opening e distribut r cured in the housing and having clined upper end, an axial bore st base of the distributor, oppositely inclined surface on its exterior. and openings lead ing; from the bore out through the di tributer below the high end of the inclined surfaces, and a deflector having a stern e1:- tcnding through the opening of the housing and adjuste'bly secured to the tapering end of the distributor.
